This is expected; /dev would usually be empty until devfs is mounted.

Looking into the unmounted /dev via the last zfs snapshot of your
/ filesystem should also be empty:

$ ls -AFGhl /.zfs/snapshot/$(ls -rt /.zfs/snapshot/ | tail -1)/dev
total 0

If it's not I'd guess these are stray garbage from BE experiments
where /dev wasn't mounted and various scripts & tools tried to pipe
via /dev/{fd,zero,null,...}.

If you created a hypothetical "empty" BE from scratch, unpacked
src tarballs into it, it would also be empty.
